spywareblaster will not open

Spywareblaster will not open so I uninstalled it and re-installed it, still will not open, requests UAC permission and given but still will not open then a message pops up saying failed to create IDespatch.
Any ideas please?

In my personal opinion, software like Norton & McAfee & now AVG is all bloated with extra gadgets. I think it maybe a good idea just to try and revo McAfee, give pc a quick clean with ccleaner, reboot and then try and install Spywareblaster. If Spywareblaster does install then re instate McAfee and see how that goes.

Avira is ok, but unless it's a paid for version, then it gives nil protection with email clients installed on your pc.

UAC can be turned off (If you wish):
1, Click start
2, Type in "start search" msconfig & press enter.
3, Once the "System Configuration" windows comes up, click on the Tools tab.
4, Scroll close to the bottom and look for "Disable UAC"
5, Once you have clicked Disable UAC, then click the "Launch" button.
A cmd window will appear, just close that. Now reboot.
